SCREW-MACHINE.

SPECIFICATION forming part of Letters Patent No. 589,144, dated August31, 1897.

Application filed April 23, 1897 Serial No. 633,531. (No model.)

To all whom it may concern.-

Be it known that we, HENRY B. SARGENT, of the city of New Haven, andALBERT A. PAGE, of the town of East Haven,in the county of New Haven,State of Connecticut, have invented a new and useful Improvement inScrew-Machines, fully set forth and described in the followingspecification, taken in connection with the accompanying drawings, whichform apart thereof, and in which- Figure 1 is a side elevation of ascrew-machine embodying our invention; Fig. 2, a transverse verticalsection on lines 2 2 of Fig. 1; Figs. 3 and 4, enlarged detail views ofthe separator and casting in front and side elevations, respectively;and Fig. 5, a vertical section on lines 5 5 of Fig. 3.

In all figures similar letters of reference represent like parts.

This invention relatesto screw-machines; and it consists in a novelconstruction of separators or mechanism for separating the chips andshavings from the stock, and is more particularly a modification of theseparatorand conduit shown and claimed in another application made byus, executed on even date herewith, filed in the United States PatentOffice on the 23d day of April, 1897, and numbered 633,530.

The invention is illustrated as applied to a single-spindle machineresembling that in the application referred to, and in which Arepresents the bed of the machine, with standards a, a, and a and B arevolving spindle rotated by the pulley b. A collar C, operated by alever D, forces the jaws E to grip the stock or blank X. A shaft G,loosely journaled in the supports a and a is rocked by adogg, engagedbya cam H and reciprocated by a second cam J, mounted on a shaft I.

- On the shaft G is secured a tool-holder K,

k and is brought into engagement with the stock by the dog g rocking theshaft against the tension of spring M. The tool first engages With theend of the blank near the spindle B or jaws E, but gradually movestoward the other end as shaft G is forced toward the left, Fig. l, bycam J. A support N on a second rocking shaft n, Fig. 2, is adapted tobear on the opposite side of the blank from the tool L while the tool isin operation to steady the work. When the tool is disengaged from thestock or the stock is about to be discharged from the jaws E of thespindle B, the support N is rocked toward the left, Fig. 2, to preventits interference with the stock when falling into its proper receptacle.

In the construction shown in the accompanying drawings the separator fordeflecting the chips as they are cut on the blank and the conduit forguiding the chips in the desired direction into theproperreceptaole areformed integral, the whole being adj ustably mounted on the tool-holder.

The casting O, embracing the separator and conduit, is formed with alongitudinal concavity 0 to make the conduit, the lower end of which, P,is adapted to fit over any suit able receptacle to receive the chips orshavings as they fall. The upper end of the conduit 0 extends tosubstantially beneath thepoint of engagement between the tool L andblank X. At this upper end of the casting is a nose-piece R, projectingin the direction of the stock and provided at its functional end withtwo contiguous slots 4 and r, the one, r, being vertical, the other, 0*,horizontal. The upper edge r of the slot 7" forms theseparating-surface, and when in operation the engaging end of the tool Lprojects into the horizontal slot r of the separator and extends intothe vertical slot 4", so as to leave a slight clearance between it andthe separator N, Fig. 5. J

The casting O is adapted to be attached to the tool-holder by means of'acircular'slot Q, which fits over the cylindrical shank of bolt It. Athumb-screw q secures the casting to the bolt of the tool-holder K, sothat the proper relation is established between the separating edge rand engaging-point of the tool L.

The operation of the device is as follows: \Vhen the tool-holder rockson its shaft to bring the tool in contact with the blank, the separatorR, being mounted on the toolllolder, is brought into such proximity withthe cutting edge of the tool L that the chips or shavings arising fromthe stock or blank extend into the clearance between the tool andseparating edge 0' and are deflected or guided by the separating edgeinto the interior of the separator. As the conduit is formed integralwith the separator, the chips forced into the interior of the latterfall naturally through the former into the receptacle placed beneath.The chips produced by the operation of the tool on the stock are therebyseparated from the stock while it is still being operated upon and areguided in the desired direction. \Vhen the tool holder is rocked awayfrom the blank, the separator and conduit are together removed fromtheir position near the blank or now-finished product,-which may beejected from the spindle to fall freely without possible interferencefrom these mechanisms. By the formation of the casting O to embrace theseparator and conduit a simple construction is produced which permitsboth parts to be simultaneously adjusted to the tool.

Having now described our invention, which may vary greatly withoutdeparting from the spirit thereof and may be applied to different typesof machines and styles of tool-holders, what we claim, and desire tosecure by Letters Patent, is

1. In a screw-machine, the combination with a rotary spindle forcarrying stock or blanks; of a tool-holder; a tool mounted thereon toengage with the stock carried by the spindle; an integral device, thebody portion of which comprises a conduit for guiding the chips from thestock, and the upper end a separator adapted to fit over and in closeproximity with the end of the tool when engaging the stock, to deflector guide the chips from the stock into the conduit, substantially asdescribed.

2. In a screw-machine, the combination with a rotary spindle forcarrying stock or blanks; of a tool-holder a tool mounted thereon toengage with the stock carried by the spindle; and an integral deviceadapted to move synchronously with the tool-holder and the body of whichforms a conduit for guiding the chips from the stock; and the upper enda separator formed integral with said conduit and adapted to fit overand in close proximity with the end of the tool when engaging the stoek,to deflect or guide the chips from the stock into the conduit,substantially as described.

3. In a screw-machine, the combination with a rotary spindle forcarrying stock or blanks; ofa tool-holder; a tool mounted thereon toengage with the stock carried by the spindle; and an integral devicemounted on the tool-holder and the body portion of which forms a conduitfor guiding the chips from the stock; and the upper end a separatoradapted to fit over and in close proximity with the end of the tool whenengaging the stock, to deflect or guide the chips from the stock intothe conduit, substantially as described.

l. In a screw-machine, the combination with a rotary spindle forcarrying stock or blanks; of a tool-holder; atool mounted thereon toengage with the stock carried by the spindle; and an integral deviceadjustably mounted on the tool-holder and the body portion of whichforms a conduit for guiding the chips from the stock; and the upper enda separator adapted to fit over and in close proximity with the end ofthe tool when engaging the stock, to deflect or guide the chips from thestock into the conduit, substantially as described.

5. In a screw-machine, the combination with a spindle for carrying stockor blanks; of a tool-holder; a tool mounted thereon to engage with thestock carried by the spindle; and a conduit adjustably mounted on thetool-holder and extending from substantially beneath the point ofengagement between the tool and stock to guide the chips from the stockin their proper direction, substantially as described.

6. In a screw-machine, the combination with a rotary spindle forcarrying stock or blanks; of a rocking reciprocating shaft; atool-holder mounted thereon for carrying the tool and bringing it intoproper engagement with the stock; and an integral device mounted on thetool-holder and the body portion of which forms a conduit for guidingthe chips from the stock, and the upper end a separator adapted to fitover and in close proximity with the end of the tool when engaging thestock, to deflect or guide the chips from the stock into the conduit,substantially as described.
